Poseidon Resources, the company that built and operates the Carlsbad seawater desalination plant, is in violation of its California Coastal Commission permit for the restoration of wetlands habitat at the San Diego National Wildlife Refuge in South San Diego Bay.

A permit the commission approved April 30, 2021, required Poseidon to start the restoration work by Oct. 30, 2021, according to a staff report prepared for next week’s Coastal Commission meeting. The work has not started, although it is on track to begin this fall.
